I am trying to move 2 files from current directory (/base/level1/level2) to one directory below (/base/level1)
Is there any easier command other than mv file1 /base/level1 ? I'm trying to understand if we have some command that move it to a specific level up or down in the current folder structure.
TIA!
My solution to this one is navigating to the path where I want to move the file and run the following command.
cp ./level2/file1 .
or
cp ./file1 ./level2/file1
Please share other solutions as well
Thanks,
AMK
You could use wildcards if the 2 files have something uniquely in common.
ie. mv file*.ext path/to/new/dest/
This will move all files starting with "file" and ending with the extension ".ext" to the destination. Have a look at this and this which will explain wildcards a bit more
You can always use .. for "one directory up".
And you can give more than 2 arguments to mv, the last always being the destination.
So mv file1 file2 .. would move those 2 files a directory up.
Or mv * .. to move all files.

Here is what my directory looks like:
Test ----
|
|----One
|
|----Two
I am attempting to list the contents of Two while still being in One and I am not able to do so.
I have tried this command (as seen in a other post) : "ls Test/" and it says No such file or directory. I have also tried ls Test/Two/ and it still does not work.
If you are in One and you want to list the contents of Two, you should go up to the parent directory using ..:
ls ../Two
../ will place you in the Test directory, from there, you can go to Two with no problem. If you have more depth levels, just add more ../ to go up one directory each time, but mind which is your current directory when running the command.
what does this command provide you in terminal.
ls -al Test //a flag is used for hidden file
I have a set of directories with files and I want to get a clean list of the absolute paths of all the files in these directories, something like this
Having
\home\me\DirA\
fileA
fileB
some_directory_that_i_dont_want_listed
\home\me\DirB\
fileB
fileC
....
\home\me\DirXYZ\
fileOPQ
and get
\home\me\DirA\fileA
\home\me\DirA\fileB
\home\me\DirB\fileB
\home\me\DirXYZ\fileOPQ
Is this possible with a ls command?, I've tried ls with -R but it lists only the filenames.
Try this command:
$ find /home/me/Dir[AB]
Hope this helps! :)
For the case it's of use to anyone, it's simple
find /home/me
lists everything with absolute paths.
If you need to filter a specific extension
find /home/me -name *.someExt
I am trying to rename multiple files with extension xyz[n] to extension xyz
example :
mv *.xyz[1] to *.xyz
but the error is coming as - " *.xyz No such file or directory"
Don't know if mv can directly work using * but this would work
find ./ -name "*.xyz\[*\]" | while read line
do
mv "$line" ${line%.*}.xyz
done
Let's say we have some files as shown below.Now i want remove the part -(ab...) from those files.
> ls -1 foo*
foo-bar-(ab-4529111094).txt
foo-bar-foo-bar-(ab-189534).txt
foo-bar-foo-bar-bar-(ab-24937932201).txt
So the expected file names would be :
> ls -1 foo*
foo-bar-foo-bar-bar.txt
foo-bar-foo-bar.txt
foo-bar.txt
>
Below is a simple way to do it.
> ls -1 | nawk '/foo-bar-/{old=$0;gsub(/-\(.*\)/,"",$0);system("mv \""old"\" "$0)}'

Here is another way using the automated tools of StringSolver. Let us say your first file is named abc.xyz[1] a second named def.xyz[1] and a third named ghi.jpg (not the same extension as the previous two).
First, filter the files you want by giving examples (ok and notok are any words such that the first describes the accepted files):
filter abc.xyz[1] ok def.xyz[1] ok ghi.jpg notok
Then perform the move with the filter it created:
mv abc.xyz[1] abc.xyz
mv --filter --all
The second line generalizes the first transformation on all files ending with .xyz[1].
The last two lines can also be abbreviated in just one, which performs the moves and immediately generalizes it:
mv --filter --all abc.xyz[1] abc.xyz
DISCLAIMER: I am a co-author of this work for academic purposes. Other examples are available on youtube.
I think mv can't operate on multiple files directly without loop.
Use rename command instead. it uses regular expressions but easy to use once mastered and more powerful.
rename 's/^text-to-replace/new-text-you-want/' text-to-replace*
e.g to rename all .jar files in a directory to .jar_bak
rename 's/^jar/jar_bak/' jar*
I have a directory structure something like :
/etc/home/d1/d2/d3/d4
The last directory d4 contains some files so it is not empty.
But by mistake I forgot to create one more directory in between say d0
So I need to change my directory structure to :
/etc/home/d0/d1/d2/d3/d4
So my question is - is there any way to introduce this new directory in existing path or I have to do all the donkey work? :P
Create a directory under your home directory with name d0. Then use the mv command to move d1 to d0. All directories and files under d1 should get moved to d0 giving you the desired structure.
mkdir /etc/home/d0
mv /etc/home/d1 /etc/home/d0
This is quite different from the single command (when /etc/home/d0 does not exist as a directory):
mv /etc/home/d1 /etc/home/d0
That might be a little confusing. The first creates a directory and moves the hierarchy into it. The second just renames one level in the hierarchy, which was not what you wanted.
I have a feeling that I already know the answer to this one, but I thought I'd check.
I have a number of different folders:
images_a/
images_b/
images_c/
Can I create some sort of symlink such that this new directory has the contents of all those directories? That is this new "images_all" would contain all the files in images_a, images_b and images_c?
No. You would have to symbolically link all the individual files.
What you could do is to create a job to run periodically which basically removed all of the existing symbolic links in images_all, then re-create the links for all files from the three other directories, but it's a bit of a kludge, something like this:
rm -f images_all/*
for i in images_[abc]/* ; do; ln -s $i images_all/$(basename $i) ; done
Note that, while this job is running, it may appear to other processes that the files have temporarily disappeared.
You will also need to watch out for the case where a single file name exists in two or more of the directories.
Having come back to this question after a while, it also occurs to me that you can minimise the time during which the files are not available.
If you link them to a different directory then do relatively fast mv operations that would minimise the time. Something like:
mkdir images_new
for i in images_[abc]/* ; do
ln -s $i images_new/$(basename $i)
done
# These next two commands are the minimal-time switchover.
mv images_all images_old
mv images_new images_all
rm -rf images_old
I haven't tested that so anyone implementing it will have to confirm the suitability or otherwise.
You could try a unioning file system like unionfs!
http://www.filesystems.org/project-unionfs.html
http://aufs.sourceforge.net/
to add on to paxdiablo 's great answer, i think you could use cp -s
(-s or --symbolic-link)
which makes symbolic links instead of literal copying
to maybe speed up or simplify the the bulk adding of symlinks to the "merge" folder A , of the files from folder B and C.
(i have not tested this though)
I cant recall of the top of my head, but im sure there is some option for CP to NOT overwrite existing, thus only symlinks of new files will be "cp -s" ed
